Travelling can simply be a human walking although if it is a fairly short distance it is not considered travelling as such. Travel is usually assisted by a man made vehicle which (depending on what it is) can move quite quickly. The four most common modes of transport are water transport (ferries, hover crafts), trains, cars or aero planes. These modes each depend on their environment and are directly affected by the elements. If weather becomes extreme there is a likelihood they will be unable to function. Each of these modes of transport runs on fuel, such as petrol along with other components. Modes of transport along with household appliances have come under scrutiny due to their emissions of carbon dioxide gases and the harmful effect this has on the environment. That said it will come as no surprise that there are now ‘green’ modes of transport are popping up everywhere and we are being encouraged to use them wherever we can.

 The electric car is a more common sight on our roads now. Local authorities have even installed chargers for these cars on streets making it easier for people to own one. Eco scooters are now more widely available as well. For the journeys more further afield some ships and other modes of water transport have devices on them that responsibly recycle waste water instead of pumping it into the sea. This waste water could contain harmful chemicals from cleaning fluids so disposing of these in the right way is an important step forward. Smaller vessels now come in a range that is run on solar energy, a good option for the more ethically minded traveler. Airlines are constantly looking at ways to cut their emissions. They realize their customers are becoming more aware of reducing their carbon footprint and will look to airlines to see where they are making changes.
